However, state\u2010of\u2010the\u2010art metal or ceramic thermistors are rigid and bulky, whereas polymer and hydrogel sensors lose conductivity or drift severely below \u2212150\u00b0C, making robust cryogenic sensing extremely challenging. Herein, we design a ZIF\u20108\u2010derived nanoporous carbon as a cryogenic thermistor material by rational defect engineering. By tuning the carbonization temperature, the heteroatom\/vacancy defect landscape (N, O, Zn, and carbon vacancies) is programmed to balance percolated graphitic pathways and dense ionized impurity centers, leading to ionized\u2010impurity\u2010scattering\u2013dominated transport at deep cryogenic temperatures. The printed carbon thermistors exhibit a wide operating window from 150 to \u2212190\u00b0C, a high cryogenic temperature coefficient of resistance (TCR) up to \u22124.7%\/\u00b0C, a temperature resolution of 0.05\u00b0C, and a response time of 0.58 s. After 100 days of immersion in liquid nitrogen, the TCR drift remains within \u00b10.2%, evidencing outstanding long\u2010term cryogenic stability.
